Just got my blackberry yesterday (had worked for a company that provide a pearl when they first came out but have since just had a regular phone and decided to take the plunge again ) and I was wondering which OS 4.5 if any at the top of this forum will work for the 8330 from Verizon. Sorry if this is a very newbie post but I look forward to getting up to speed fast and becoming a very active member of this community!
